Question

A total of 399 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answer 1

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$2y+y=399\\3y=399$

Dividing both sides by 3

$\frac{3y}{3}=\frac{399}{3}\\y=133$

133 adult tickets were sold.
